"That is one of the reasons numbers matter: they build on themselves, speaking to the part in each of us that doubts change can really happen. But numbers also say something to the larger world; they are the basic currency a movement relies on. The fossil-fuel industry represents the one per cent of the one per cent; lacking scientific arguments, its advocates use their only asset, an unparalleled pool of cash, to maintain the status quo. If the rest of us are going to shake up the planetary gestalt, our equivalent currency is bodies—and the passion, spirit, and creativity they contain." - Bill McKibben, Among the Marchers - The New Yorker
